Discovery of a new antibiotic against resistant pathogens
Discovery of a new antibiotic against resistant pathogens
For a long time, antibiotics were considered a silver bullet against bacterial infections. Over time, many pathogens have adapted to resist antibiotics, so the search for new drugs is becoming increasingly important. An international team of researchers including scientists at the University of Basel, has now discovered a new antibiotic by computational analysis and deciphered its mode of action.

Recycling, a way for plants to survive in case of shortage
Recycling, a way for plants to survive in case of shortage
In order to secure a place in the sun and to guarantee their growth, plants have developed different strategies. But what happens when plant density is so high that resources, especially light, run out? Plants go into survival mode and activate a recycling mechanism: autophagy. This process is at the heart of a study published on October 10, 2022 in "Nature Communications" by the team of Prof. Christian Fankhauser at the Integrative Genomics Center of UNIL .

Flexible solar cells with record efficiency of 22.2%
Flexible solar cells with record efficiency of 22.2%
One year after announcing an efficiency record, scientists have achieved a new mark of 22.2% for flexible CIGS solar cell on polymer film. Solar cells of this type are especially suited for applications on buildings, vehicles, satellites, airships, and mobile devices. researchers have - once again - improved the efficiency of CIGS flexible solar cells.

Nanomaterial from the Middle Ages
Nanomaterial from the Middle Ages
To gild sculptures in the late Middle Ages, artists often applied ultra-thin gold foil supported by a silver base layer. For the first time, scientists at the Paul Scherrer Institute PSI have managed to produce nanoscale 3D images of this material, known as Zwischgold. The pictures show this was a highly sophisticated mediaeval production technique and demonstrate why restoring such precious gilded artefacts is so difficult.

The days of the generalist are gone. Long live the specialist!
In science, specialization pays off - at least when it comes to career impact. That's the finding of a team of researchers who looked specifically at this subject. Is it better to be a generalist or a specialist? Gaétan de Rassenfosse, who holds the Chair of Innovation and IP Policy at EPFL, set about answering this question by digging through data on more than 30,000 biomedical researchers.

Non-native species are also beneficial to the ecosystem
Non-native species are also beneficial to the ecosystem
A team of scientists makes the case for reevaluating maligned non-native species. Awareness of non-native species - often called ''invasive'' - has vastly increased over the past fifty years, to the point where anyone with green conscience has heard of them and their negative effects, whether it is the zebra mussel or ragweed.

With new ponds against amphibian extinction
With new ponds against amphibian extinction
Nature conservation pays off: amphibians benefit from new ponds - despite many causes of endangerment that still affect them. This is what researchers from WSL and Eawag found in a joint study using data from amphibian monitoring in the canton of Aargau. The study was published in the scientific journal PNAS.

Alpine fish biodiversity is amazingly young
Alpine fish biodiversity is amazingly young
A high fraction of the endemic biodiversity of the Alps is very old. The endemics - species found only in a confined area - have developed over the past millions of years during the cycles of glacial and interglacial periods or even before these cycles began. Fish, however, are an exception: most endemic fish species emerged only after the end of the last ice age about 15,000 years ago.

Zinc could treat a rare genetic disorder
Zinc could treat a rare genetic disorder
By deciphering mutations in the GNAO1 gene, which cause severe mental and motor disabilities, a team from the University of Geneva is showing how zinc could improve the brain defects at stake. Paediatric encephalopathies of genetic origin cause severe motor and intellectual disabilities from birth. One of these diseases, first identified in 2013, is caused by mutations in the GNAO1 gene.

Mapping human brain development
Mapping human brain development
Researchers at ETH Zurich are growing human brain-like tissue from stem cells and are then mapping the cell types that occur in different brain regions and the genes that regulate their development. The human brain is probably the most complex organ in the entire living world and has long been an object of fascination for researchers.

Stabilizing polarons opens up new physics
Stabilizing polarons opens up new physics
Physicists at EPFL have developed a formulation to solve the longstanding problem of electron self-interaction when studying polarons - quasiparticles produced by electron-phonon interactions in materials. The work can lead to unprecedented calculations of polarons in large systems, systematic studies of large sets of materials, and molecular dynamics evolving over long time periods.

Discovering New Cancer Treatments in the 'Dark Matter' of the Human Genome
Discovering New Cancer Treatments in the ’Dark Matter’ of the Human Genome
Researchers of the University of Bern and the Insel Hospital, University Hospital Bern, have developed a screening method to discover new drug targets for cancer treatment in the so-called -Dark Matter- of the genome. They applied their method to non-small cell lung cancer (NSCLC), the greatest cancer killer for which effective therapies are urgently sought.

New function of the cerebellum
New function of the cerebellum
The cerebellum is known primarily for regulation of movement. Researchers at the University of Basel have now discovered that the cerebellum also plays an important role in remembering emotional experiences. The study appears in the journal PNAS. October 2022 Both positive and negative emotional experiences are stored particularly well in memory.

Researchers deliver science for humanitarian action
Researchers deliver science for humanitarian action
Using innovative technologies and scientific expertise to help people in need is the goal of the Engineering for Humanitarian Action initiative launched by the ICRC, ETH Zurich and EPFL in 2020. Six of the projects are already offering results for tangible improvements for the ICRC. "By highlighting key sustainability principles in a simple way, the tool will help us make more informed decisions when designing our construction projects," says ICRC's Pavlos Tamvakis.

Group size enhancement explains cooperation in fishes
Group size enhancement explains cooperation in fishes
The survival chances of group members are often greater in large than in small groups. In some species, non-reproducing group members therefore help raising offspring, even if they are unrelated. In an experimental study, researchers at the University of Bern investigated this seemingly altruistic behavior in cooperatively breeding fishes.

Less noise and better fuel efficiency during approach
The approach and landing of passenger jets is often a burden for people and the environment. The DYNCAT project, in which researchers are working with partners in Switzerland, Germany and France, is aiming at approaches that cause less noise and CO2 emissions - thanks to intelligent assistance systems for the pilots.

Researchers want to make salt printing marketable
Materials scientists Nicole Kleger and Simona Fehlmann have developed a 3D printing process for creating salt templates that they can fill with other materials. One area of application is the creation of highly porous lightweight metal components. The two Pioneer Fellows are now trying to transfer this process to industry.

Computational shortcut for neural networks
Computational shortcut for neural networks
Neural networks are learning algorithms that approximate the solution to a task by training with available data. However, it is usually unclear how exactly they accomplish this. Two young Basel physicists have now derived mathematical expressions that allow one to calculate the optimal solution without training a network.
